Mainjiniya akamatchula chitsulo chosapanga dzimbiri chowongolera madzimadzi ofunikira kwambiri kapena zinthu zozungulira kwambiri, samangosankha kukana dzimbiri - akubetcherana pa kukhazikika kwapang'onopang'ono panjinga yotentha, kusakhulupirika kwapang'onopang'ono pambuyo pa kupanga makina, ndi kubwereza-bwereza kwa batchi pamakina. Chifukwa chake kusankha koyenera zitsulo zosapanga dzimbiri zitsulo jekeseni akamaumba fakitale siziri za kuchuluka kapena mtengo wokha. Ndizokhudza kuwongolera zitsulo, kutsata njira, komanso chidziwitso chotsimikizika chokhala ndi magawo omwe amalephera mowopsa ngati porosity ipitilira 0.8% kapena mpweya wa boundary carbide umasintha ngakhale 5 ° C panthawi ya kutentha.
Chifukwa Chake Chitsulo Chosapanga dzimbiri MIM Imafuna Zambiri Kuposa Nkhungu ndi Ng'anjo
Tawona ma projekiti ambiri akuyimitsidwa - osati pakuwunika kapangidwe kake, koma poyang'ana nkhani yoyamba - chifukwa wogulitsa adatenga zitsulo zosapanga dzimbiri MIM ngati 316L bar stock. Mitundu yolephereka yadziko lenileni imafotokoza nkhaniyi: kumenyera nkhondo mu matupi a valve okhala ndi mipanda yopyapyala pambuyo pa sintering; kuuma kosagwirizana kudutsa ndodo ya pistoni ya 12-mm-diameter chifukwa cha kufalikira kwa mpweya wosiyana; Kubowoleza pamwamba m'nyumba zapampu pambuyo pa maola 48 akuyesa utsi wa mchere chifukwa kuchotsa zomangira kumasiya mabakiteriya a sulfure.
Chitsulo chosapanga dzimbiri MIM chimagwira ntchito pokhapokha ngati zinthu zitatu zikugwirizana: Choyamba, zopangira ziyenera kukhala ufa wopangidwa ndi gasi wokhala ndi O₂ ≤ 150 ppm ndi morphology yozungulira> 95% -osati zosakaniza zamadzi zomwe zimagulitsidwa ngati "MIM-grade." Chachiwiri, kutulutsa kuyenera kutsata mawonekedwe otenthetsera amitundu yambiri omwe amawunikidwa pagawo lililonse, osati dongosolo la uvuni wokhazikika. Chachitatu, kupukuta kumafuna vacuum kapena chiyero cha hydrogen mpweya wokhala ndi mame ≤ -60°C. Dumphani imodzi, ndipo mumalandira zigawo zomwe zimadutsa macheke a CMM koma zimasweka pa 72% ya kuphulika kwamphamvu.
Ichi ndichifukwa chake timatengera dongosolo lililonse la zitsulo zosapanga dzimbiri la MIM ngati mgwirizano wazitsulo-osati kupanga. Timayamba ndi certified powder traceability mpaka nambala ya batch yosungunuka, kutsimikizira kutentha kwa binder pogwiritsa ntchito ma curve a TGA-DSC, ndikuyang'anira kutentha kwa ng'anjo mu nthawi yeniyeni ndi quadrupole mass spectrometry. Palibe kuchotserapo.
Kumene Precision Engineering Imakumana ndi Zowona Zamakampani
Mafakitole ambiri azitsulo zosapanga dzimbiri a MIM amapambana pamawotchi kapena zida zamano - magawo ochepera 50g, kupsinjika kochepa, osasindikiza ntchito. Koma ntchito zamafakitale zimafuna zambiri: ma valve opanikizika omwe amagwira ntchito pa bar 420, ma silinda okhala ndi ± 5 µm concentricity kudutsa 200 mm kutalika, ma winch center shaft rollers onyamula katundu wa 12-ton dynamic. Izi si zovuta za geometry. Awa ndi zovuta zamakhalidwe azinthu.
Tapereka zida zopitilira 18,000 zazitsulo zosapanga dzimbiri za MIM zama hydraulic system pomwe kutayikira kumatanthawuza kuyimitsidwa kwa makina - komanso pomwe pulagi imodzi yolephera ya AMS 5387 cobalt-alloy idayambitsa $240k mu nthawi yopuma. Yankho lathu? Hybrid processing. Timaumba ma geometry ovuta, kenako makina osindikizira a CNC ofunikira mpaka Ra 0.2 µm ndikumangirira manja osapanga dzimbiri kuti akhale mabowo onyamula katundu. Uku sikunyengerera-ndikuyika bwino.
Malo athu ogwirizana ndi ISO amakhala ndi mizere yodzipereka ya MIM ya 17-4PH, 420 zosapanga dzimbiri, ndi magiredi awiri okhazikika - iliyonse imakhala ndi mapokedwe osiyana a ufa, kusungirako zida, ndi ng'anjo zamoto. Palibe kuipitsidwa. Palibe zomangira zogawana. Magawo aliwonse amapeza chitsimikiziro chathunthu cha chemistry kudzera mu OES, kuyeza kachulukidwe, komanso kuyesa kwamphamvu pa zitsanzo za mboni zomwe zimakokedwa mu tray yofananira monga magawo opanga.
Zimene Mumapeza—Osati Zimene Zinalonjezedwa
- Kufufuza kwazinthu: Zikalata zaufa, mafayilo a sintering log, ndi malipoti a CMM olumikizidwa ndi gawo lililonse la ID-osati manambala a batch okha
- Palibe "standard" kulolerana: Timagwira mawu oyitanitsa a GD&T pachinthu chilichonse-mwachitsanzo, kulolerana kwa Ø0.05 mm pamabowo omangika, kusanja kwa 0.015 mm pakusindikiza nkhope - kutengera maphunziro enieni aukadaulo, osati matebulo amndandanda
- Chitsimikizo chogwira ntchito chikuphatikizidwa: Zotengera zilizonse zimatumiza zokhala ndi zolemba zoyeserera za hydrostatic (zagawo zokhala ndi kupsinjika) ndi mamapu akukalipa pamwamba-palibe ndalama zowonjezera
- Ndemanga za Design-for-MIM mkati mwa maola 48: Osati "khoma ili ndi lopyapyala kwambiri" - koma makulidwe enieni enieni a giredi yomwe mwasankha, mapu oneneratu kuti adzachepa, komanso malo omwe ali pachipata kuti mupewe mizere yowotcherera munjira zovuta kwambiri.
Sitimapereka "MIM-yokha" kapena "machining-only". Timapereka ntchito-yoyamba kupanga. Ngati gawo lanu lachitsulo chosapanga dzimbiri likufunika kuchulukira kwa mawonekedwe a ukonde komanso kusamalidwa bwino, timaphatikiza zonse ziwiri-popanda kulandila, popanda kutayika kwa data, osaimba mlandu njira ina ikavuta.
Kusankha Kupitirira Kabukuko
Funsani kuthekera kulikonse zitsulo zosapanga dzimbiri zitsulo jekeseni akamaumba fakitale mafunso atatu awa—ndipo onani momwe akuyankhira:
- Ndiwonetseni mitengo itatu yomaliza ya ng'anjo ya 17-4PH. Kodi mpweya wa okosijeni unachitika kuti, ndipo ndi njira yotani yowongolera?"
- "Ndiwongolereni pa ndondomeko yanu yochotsa zomangira kuti mukhazikitse zida zochindikala 3.2 mm. Kodi mumatenthetsa kutentha kochepera 350 ° C ndi chifukwa chiyani?"
- "Ngati kujambula kwathu kumafuna HRC 42-44 pampando wa valavu 420 wosapanga dzimbiri, kodi mumakwaniritsa izi kudzera mu ukalamba wa post-sinter - kapena mumasintha mawonekedwe a sintering ndikudalira kuuma kwa mvula kokha?"
Ngati yankho ndi losamveka bwino, lachizoloŵezi, kapena maumboni a "miyezo yamakampani" osatchulapo ASTM B964 kapena MPIF Standard 35, pitirizani kuyang'ana. Chitsulo chosapanga dzimbiri cha Precision MIM chili ndi ziro malo ongoganizira.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imamanga mbali zomwe zimakhala zosindikizidwa pa 200 ° C, zimazungulira popanda kugwedeza pa 1500 RPM, ndikupulumuka maulendo a 10,000 popanda kuyambitsa microcrack. Timachita izi pokonza ufa wa chitsulo chosapanga dzimbiri gilamu iliyonse ngati chitsulo chosapanga dzimbiri—osati chinthu chamtengo wapatali. Pitani ku https://www.tsingtaocnc.com kuti muwunikenso zolemba zaukadaulo, kutsitsa ziphaso, kapena perekani gawo lanu lotsatira la zitsulo zosapanga dzimbiri kuti muunike momwe mungapangire.
